Which risk increased for Inca reed suspension bridges during El Niño events?

💡 Explanation

Increased rainfall causes fibers to swell, lowering the specific tensile strength. This Fiber Hygroscopy mechanism reduces the effective load the bridge could support because water absorption weakens the fibers rather than causing erosion or quipu degradation therefore affecting load capacity.
